It is possible to get infected again after having mumps. There are several types of mumps, the most common being viral mumps, or mumps, which generally provides lasting immunity and does not lead to a second infection. However, acute bacterial mumps, which is often referred to as purulent mumps, as well as secondary mumps due to blockage of the salivary gland stones, recurrent childhood mumps, and non-specific mumps, are prone to recurrence. So even if you have had mumps, you need to be vigilant, as it may still recur.
